PECIFIGATION forming part of Letters Patent No. 544,132, dated August 6, 1895.

Applic t n fi December 14, 1894. Serial No. 551,816. (No model.)

To all whom, it may concern:

Beit known that I, JAMES D. SHoo'rs, a citizen of the United States, and a resident of [-Iorsehead's, in the county of Ghemung and State ofNew York, have invented certain new and useful Improvements in Looks for Bicycles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of-this specification.

Figure l of the drawings shows the lock applied to a bicycle. Fig. 2 is a sectional view on the line a: a: of Fig. 3, the bolt and the head of the spindle being, however, in full lines. Fig. 3 is a front elevation of the invention. Fig. 4 is a rear elevation of same. Fig. 5 is a detail of one of the lock-disks. Fig. 6 is a detail of friction-spring for locking-disks.

The object of this invention is to provide a simple, efficient, and comparatively inexpensive lock for bicycles and like vehicles, capable of being applied to any machine for the purpose of locking one of its wheels against rotation, and thus render it impracticable for any one to make off with the wheel during the absence of the rider.

With this object in view the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

In the accompanying drawings I have shown the invention as applied to the front wheel of a safety-bicycle, although it may be equally well applied tothe rear wheel. The lock which controls the bolt is of that class known as combination or permutation locks.

In the drawings, the letter A designates the lock-case, which is shown as consisting of a short cylinder closed at both ends and formed in two sections united by screw-threads.

B designates'the bolt-barrel, which is preferably formed integrally with one of the casesections and projects therefrom eccentrically in a plane parallel with the axis of the case.

0 designates the attachment clip, which is adapted to embrace one of the forks or other portion of the frame, being formed in two sections, one of which is integral with the case and the other removable. The stationary section is bent at one end portion upon each side of the barrel B to form lips c, which receive laterally-turned flanges c of the removable section. A screw 0 through perforated lugs c at the opposite ends of the sections, secures them together and the lock in place.

D designates the bolt, which works through an opening at in the outer face of the case, through which it extends into the said barrel. A head or flange e limits the inward throw of the bolt, while a corresponding head or flange 6 limits the opposite throw. This'head or flange 6 consists of acap-screw seated in the outer end of the bolt.

e designates a small spring seated in the bolt to prevent rattle of the same. Near its opposite end the bolt is formed with a series of adjacent circumferential groovesf. Three of such grooves are shown in the present instance, but the number may be varied to correspond with the number of disks of the particular lock employed.

The lock consists'of a spindle E, which is journaled in the ends of thecase, being prevented from pulling out by means of the capscrew 9 engaging one end'thereof, the head of said screw seating in a countersunk aperture in the stationary sections of the attachment clip. The spindle is formed with a boss H, which extends slightly through the outer end wall of the case into the chamber thereof,

being provided on itsinner face with a stud or pin h. r

I are three disks which are rotatably seated upon the said spindle, being spaced slightly from one another by means of bosses t' thereon. Each of said disks, with the exception of the last one, has on each face a projecting stud or pin it, the last disk having such stud or pin upon one face only. Each. of said disks is also formed with a peripheral notch or concavity is. The relation of these disks to the bolt is such that when the bolt is shot through or into the wheel its circumferential grooves f will be engaged by peripheral portions of the three disks, it being impossible to move the bolt until said disks have been so operated as to bring into alignment adjacent to said bolt the three notches or concavities 7c. The outer end portion of the spindle has a milled head or button Z, and also carries an apertured dial-plate L, which is rotatably seated in the outer face of the case.

In Fig. 3 I have shown the face of the case as having thereon letters which appear through the apertures of the dial-plate. Such letters, together with the initial letter S on the outer end of the bolt, are shown as spelling the word safety.

The rotation of the disks upon turning the spindle is effected through the engagement of the pins h and It.

A friction-spring m is provided to retain the disks in stationary position when once they have been brought to the proper points in working the combination, which is effected by rotating the spindle in alternate directions in the usual manner, in accordance with the predetermined formula or combination.

The boss H and the series of disks are each provided with a plurality of holes, in any one of which their respective pins may be placed in order to effect different combinations. The combinations may be further varied by different markings of the dial-plate.

In order to prevent the bolt when released from being accidentally thrown between the spokes I form thereon two circumferential grooves 12. These grooves are so disposed that by slightly turning the spindle (the bolt being withdrawn) the edge of the opening in the dial-plate will engage one of said grooves, and the first disk will engage the other, thus preventing the bolt from moving.

hen the rider desires to leave his wheel for a very short time and does not wish to set the lock, the bolt may be thrown and the dial turned alittle way only to prevent the bolt being moved back. A person looking at the lock in this position would be unable to tell that the look was not made, and it he should attempt to move the dial would be very likely to set the lock instead of releasing it.

Having thus described my invention, what I claim is-- l. The herein described lock for bicycles, comprising the sectional case, its attachment clip, its bolt barrel, the slidable bolt working in said barrel and case and having therein a series of circumferential grooves, the spindle journaled in said case, the series of notched disks rotatably seated on said spindle, an adjustable pin on said spindle, similar pins on each disk, and a dial plate also carried by said spindle, substantially as specified.

2. In a bicycle lock, the combination with the lock case, its attachment clip and bolt barre], the spindle, its apertured dial plate, and the series of notched locking disks rotatably seated on said spindle, of the bolt adapted to be slid between the spokes of one of the bicycle wheels, said bolt having therein a series of circumferential grooves, arranged to be engaged by said disks, and also other grooves adapted to be engaged by one of said disks and by the dial plate, substantially as specitied.

In testimony whereof I affix my signature in presence of two witnesses.
